As you begin to look at data structures using Java, this first assignment will have you look at the implementation of a queue and a stack. These two algorithms will be implemented using linked lists. You will complete 2 given program shells: one for a queue and the other for a stack.In addition, you will establish your Key Assignment template that you will build in Week 1, and each week, you will add material to the appropriate section of the document.Your Data Structures Using Java template document should be in the following format:Data Structures Using Java document shell Use MS Word Title Page Course number and name Project name Student name Date Table of Contents Use auto-generated TOC Separate page for each section Maximum of 3 levels deep Be sure to update fields of TOC so it is up-to-date before submitting your project Abstract Paper Topic Background Section Headings (Create each heading on a new page with TBD as the content except for the sections you are currently working on.) Section 1: Lists, Stacks, and Queues Section 2: Heaps and Trees Section 3: Sorting Algorithms Section 4: Searching Section 5: Recursion Conclusion References Each week, you will add to this document and submit for grading. As a preview, each section will contain the following:Section 1: Lists, Stacks, and Queues Implement 2 programs for the following: Stacks Queues Section 2: Heaps and Trees Implement pseudo code for a hash table and resolve collisions with a linked list. Section 3: Sorting Algorithms Compare sort algorithms. Section 4: Searching Implement pseudo code to search for values in a linked list or array. Section 5: Recursion Implement pseudo code to create a factorial of a number using recursion. Week 1: Assignment DetailsThe task this week is to complete the following 2 structures using a linked list:Stack Queue Assume the occurrence of a linked list node is represented by the object “Node” and its “Data” and “NextRef” attributes.Part 1: Assume a “Head” node exists with the NextRef attribute pointing to the first node in the stack or being null if the stack is empty. Create pseudo code for the following 3 stack methods, showing the logic tied to the inverted list. Include a summary of these actions. push( item )pop( )display( )Part 2: Assume “Front” and “Rear” nodes exist with the “NextRef” attributes pointing to the first and last nodes of the queue or being null if the queue is empty. Create pseudo code for the following 3 queue methods, showing the logic tied to the inverted list. Include a summary of these actions.enqueue( item )dequeue( )display( )Week 1 Deliverables:Pseudo code implemented for both the stack and queue methods Documented pseudo code Add the completed pseudo code and discussion to the Key Assignment template Section 1: Lists, Stacks, and Queues. Name the document "IT265__IP1.doc." Please submit your assignment.

Case assignment:The following scenario is based on an actual attack deconstructed at a seminarBackground:No-Internal-Controls, LLC is a mid-sized pharmaceutical company in the Midwest of the US employing around 150 employees. It has grown over the past decade by merging with other pharmaceutical companies and purchasing smaller firms.Recently No-Internal-Controls, LLC suffered a ransomware attack. The company was able to recover from the attack with the assistance of a third party IT Services Company.Attack Analysis:After collecting evidence and analyzing the attack, the third party was able to recreate the attack.No-Internal-Controls, LLC has a number of PCs configured for employee trainingThese training computers use generic logins such as “training1”, “training2”, etc. with passwords of “training1”, “training2”, etc.The generic logins were not subject to lock out due to incorrect loginsOne of the firms purchased by No-Internal-Controls, LLC allowed Remote Desktop connections from the Internet through the firewall to the internal network for remote employeesDue to high employee turnover and lack of documentation none all of the IT staff were aware of the legacy remote accessThe main office has only a single firewall and no DMZ or bastion host exists to mediate incoming remote desktop connectionsThe internal network utilized a flat architectureAn attacker discovered the access by use of a port scan and used a dictionary attack to gain access to one of the training computersThe attacker ran a script on the compromised machine to elevate his access privileges and gain administrator accessThe attacker installed tools on the compromised host to scan the network and identify network sharesThe attacker copied ransomware into the network shares for the accounting department allowing it spread through the network and encrypt accounting filesCritical accounting files were backed up and were recovered, but some incidental department and personal files were lostInstructions:You have been hired by No-Internal-Controls, LLC in the newly created role of CISO and have been asked to place priority on mitigating further attacks of this type.Suggest one or more policies that would help mitigate against attacks similar to this attackSuggest one or more controls to support each policyIdentify each of the controls as physical, administrative, or technical and preventative, detective, or corrective.Keep in mind that No-Internal-Controls, LLC is a mid-sized company with a small IT staff and limited budgetDo not attempt to write full policies, simply summarize each policy you suggest in one or two sentences.Clearly indicate how each policy you suggest will help mitigate similar attacks and how each control will support the associated policy
